PDF Remediation, Without the Per-Page Invoice
Human remediation services charge $3–10 per page and take days. The machine-checkable layer — most files' actual problem — takes minutes here.
Search for PDF remediation and you'll find quote forms: real humans retagging documents at $3–10 per page with multi-day turnaround. That's the right answer for gnarly, high-stakes documents — and massive overkill for the everyday case: a born-digital report or policy PDF that simply was never tagged. Ceereo is the self-serve lane: upload the PDF, get the free audit, and download a remediated version in minutes — tags, reading structure, artifacts, language, title, alt text — with machine verification and a pixel-diff proving the visual file is untouched.

How it works
From upload to accessible PDF in four steps
The fastest way from an inaccessible PDF to a tagged, verified one — no tag panel, no service queue, no visual changes.
- Step 1
Upload your PDF
Drop in the PDF you need to make accessible. Your file is processed only to audit and remediate it, and is never used to train models.
- Step 2
The document is audited
Every PDF/UA and WCAG machine check runs: tags, reading order, language, title, alt text, font embedding and text integrity.
- Step 3
The structure is written in
Headings, paragraphs, lists, tables and figures are tagged in reading order, with headers and footers marked as artifacts to be skipped.
- Step 4
Download the accessible PDF
Get your own file back with a full tag structure, re-audited and pixel-compared so you can prove nothing visible changed.
In short
PDF remediation means adding the accessibility layer — tags, reading order, alt text, metadata — to an existing PDF. Human services charge $3–10/page with days of turnaround; Ceereo remediates born-digital PDFs in minutes at a flat per-document price, machine-verified and visually identical.
What does PDF remediation cost?
Human remediation services typically charge $3–10 per page (complex documents higher), so a 50-page report runs $150–500. Automated remediation of born-digital PDFs costs a flat per-document price — a fraction of one page's service rate — and finishes in minutes. Scanned documents and complex forms still justify human services.
The self-serve lane
Most PDFs don't need a human — they need tags
The dirty secret of remediation queues: a large share of submitted files are clean, born-digital documents whose only crime is being untagged. Automating exactly that class — and honestly refusing scans and forms — is why this can cost dollars instead of hundreds.

Why not do it by hand?
Ceereo vs. doing it manually
Remediating a PDF by hand in Acrobat's tag panel takes days and rarely verifies clean the first time. Here's the difference.
Output quality

Frequently asked questions
When should I still hire a human service?+
Scanned documents, complex interactive forms, and documents where nuanced reading-order judgment is legally critical. For born-digital text documents, automation covers the machine-checkable layer those services bill hours for.
How is quality verified?+
The output is re-audited against the same PDF/UA machine checks and pixel-compared with the original — both results are shown before you download.
Do you keep my documents?+
